1. The problem asks to identify which postulates or theorems the LA theorem is a special case of. 2. The LA theorem (Leg Angle theorem) relates to triangle congruence criteria. 3. The main triangle congruence postulates and theorems are SAS (Side-Angle-Side), ASA (Angle-Side-Angle), AAS (Angle-Angle-Side), and SSS (Side-Side-Side). 4. The LA theorem is a special case of the AAS theorem and the ASA postulate because it involves two angles and a side. 5. Therefore, the correct answer is option C: AAS theorem and ASA postulate.
